For the aTSA patients, radiographic follow-up was available for 383 patients (73%); 113 patients had a radiolucency around at least one glenoid peg (29.
The result, according to executives, is a "beneficial set of attributes, including radiolucency, bone-like mechanical properties, and bone on-growth characteristics.
The TyWedge system marries the radiolucency of PEEK-Optima[sup.
Particularly in the orthopedic industry, where polymers increasingly are being used to enhance implant radiolucency, bone growth or bioresorbability.
In fact it has many virtues, including radiolucency, enabling monitoring of the implant in a way that is just not possible with titanium implants.
Bite-wing or orthopantomograph images reveal a well-defined, unilocular radiolucency with a smooth border, showing minimal bone expansion and even cortication; it is often associated with an unerupted tooth (figure 1).
Conventional imaging using a single plain film of the abdomen typically shows a curvilinear radiolucency outlining the bladder wall.
They are characterized by an area of architectural distortion and are defined according to the criteria of Tabar and Dean:3 (1) The presence of a central radiolucency, (2) the presence of radiating long thin spicules, (3) varying appearance in different projections, (4) radiolucent linear structures parallel to the spicules, and (5) absence of a palpable lesion or skin changes.
Grades can, for example, leverage material characteristics such as electro-magnetic interference (EMI) shielding for electronics, and radiolucency in X-Ray applications, thereby enhancing the value of light-weight, high performance, metal substitutions.
Radiographs taken with the bird manually restrained showed limited swelling and moderate sclerotic reaction on the left side of the nasal bone, with loss of the characteristic radiolucency on the proximal third of the upper beak (Fig 2).
The VEO system also features a tubular retractor made of Solvay's Radel[R] polyphenylsulfone (PPSU) resin for radiolucency and the ability to withstand repeated steam sterilization.
Radiographs of Pb-exposed animals (Figure 1B,D) show a decrease in trabecular bone in both the long bones and spine, as visualized by increased radiolucency in these regions.
